Make the iotedge module update its credentials before they expire

Gopikrishnan Bahuleyan Pillai 36

In the support request TrackingID#2408120030005983, it is mentioned that "Edge Hub periodically checks credentials of all connected modules. If any credentials are expired, it disconnects the module and expects it to reconnect".

I want to know how this happens under the hood; like will Edge kill the module and start it again.
Also, how to make the module update its credentials before they expire.
Some code samples would be really helpful.

Background : Have 2 iot egde modules. Inter module communication via direct method is failing at times. Manual restart of module makes it work. Understanding that one of the module is failing to restart/reconnect.

Currently using :

iotedge version 1.4.3,
host os: Ubuntu 20.04,
iot edge module with: Microsoft.Azure.Devices.Client 1.42.3

Hello @Gopikrishnan Bahuleyan Pillai,

welcome to this moderated Azure community forum.

I'm not sure about what there restart looks like.

You use the iotedge version 1.4. Can you test the same behavior in the 1.5 environment to see if it (the direct method calls) works there as expected?
